In order to enhance voice quality over the wireless network, SpectraLink has developed a quality of service (QoS) mechanism that is implemented in the wireless telephone and access point. This mechanism, SpectraLink Wi-Fi Voice Priority, or SVP, gives a controlled preference to voice packets over data packets on the Wi-Fi network, increasing the probability that all voice packets are transmitted efficiently. SpectraLink Voice Priority is an open specification that is compliant with the IEEE 802.11b standard.

Features

• Minimises latency for voice packets
  • Provides priority queuing for voice packets
  • Ensures predictable, timed delivery of packets
  • Provides admission control to avoid over-subscription of access points
• Implemented in wireless LAN access points, handsets, gateways, and SVP Server.
  • 802.11b-compatible
  • Software upgradeable

SVP Server Overview

The SpectraLink Wi-Fi SVP Server is the hardware component of the system that ensures excellent voice quality is maintained on a shared wireless voice and data network. The SpectraLink Wi-Fi SVP Server can support thousands of users, depending on the number of SpectraLink Wi-Fi SVP Servers and the average wireless telephone usage.

Features

• Dedicated network appliance
• Provides SVP encapsulation of voice packets to allow prioritization in access points
• Multiple configurations available to provide cost-effective scalability
  • Supports small, traditional PABX customers (<64 users) with four or fewer SpectraLink Telephony Gateways.
  • Supports large, traditional PABX customers with a maximum of 40 SpectraLink Telephony Gateways (approximate 640 users) with a single SVP Server.
  • Supports small IP Telephony customers with SVP 10 and 20 user configurations.
  • Supports large IP Telephony customers with a maximum of 16 SVP Servers (approximate 8,000 users).
